Here are some things that come in cans: soup; soda; juice; beans; vegetables; tuna and almost everything else.

The bad news is, according to a study in Hypertension, those canned things in your life can contribute to increased blood pressure, and it’s not just because of high sodium.

Researchers in South Korea found that the chemical bisphenol A (BPA), which lines many readily available canned goods, increases blood pressure 16 times higher than if you were to consume a drink out of a glass bottle. They determined this by studying the effects of soy milk consumed in glass bottles, cans and a combination of the two. The results showed that the most BPA was found after consuming out of a can, while glass bottles produced the lowest cause for concern.

Another study determined that eating canned soup five days in a row led to 1000 per cent more BPA in the human body than someone who had consumed hot bowls made from fresh produce. (This would be a good time to check out these 21 healthy winter soup recipes!)

So, you’ve got a bit of extra BPA swimming around inside of you? What’s the big deal? Well, Yun-Chul Hong, one of the authors of the study in Hypertension, says it’s concerning because of what high blood pressure could mean down the road. Hong told Time, “Because hypertension is a well-known risk factor for heart disease, our study showing the link of BPA exposure to elevation in blood pressure strongly suggests that BPA exposure may increase the risk of heart disease.”

So, the choice is yours: eat hearty homemade soups and make less of a contribution to escalating high blood pressure, or stick to salty canned soups and drinks and, well, see how it plays out.
